influxdb_2.0.0-beta backup and restore to 2.1.1 fails 'Error: no backup manifests'

__Steps to reproduce:__
List the minimal actions needed to reproduce the behavior.

1. influx backup -p ./ on source VM
2. on new VM run influx restore ./

__Expected behavior:__
DB to be restored

__Actual behavior:__
New VM shows:
Error: no backup manifests found at: xxxxxx

__Environment info:__

* System info: Linux 5.4.0-97-generic x86_64
* InfluxDB version:
* New: InfluxDB 2.1.1 (git: 657e1839de) build_date: 2021-11-09T03:03:48Z
* old: InfluxDB 2.0.0-beta.16 (git: 50964d732c) build_date: 2020-08-07T20:18:07Z

Basically I run the backup on the old VM with:
`influx backup -p /xxxxx/backup/ -t xxxxxx`
This spits out 26 tsm files and a .bolt.
and on the new VM I run:
`influx restore /xxxxx/backup`
which gives:
`Error: no backup manifests found at "/mnt/media/backup"`

If I do:
`influx backup -portable -p /xxxxx/backup/ -t xxxxxx`
I get the same result.

I'm obviously missing the meta data but I can't find anything in the documentation about backing up meta data.

Start by reproducing the reported `influx backup` and `influx restore` commands using the stated InfluxDB 2.0.0-beta.16 and 2.1.1 versions, then inspect the generated backup directory for the manifests and metadata mentioned in the report. Done means determining whether this version combination can restore successfully, or documenting the required migration or backup procedure if it cannot.
